To all cull-'om z'z may concern:

Be itltnown that. l, HARRY E. Form1-inn, a lcitizenot the United States7 residing at Augusta, in the county of Richmond and State of Georgia,- have invented al new and yuseful"Bicycle-Lock, of Whichthe following i thereof. i

A further object is to provide a lock which As cheap to niainifacture and which can be 4used either as an attachment for 'a bicycle already constructed or` which can be built onto the machine.

lilith the foregoing and other objects in view which will a-ppear'as the description prmfeeds7 the invention resides inftlie con1- bination and arrangement of parts and in the details oit' construction hereinafter described and claimed, it being; understood that lill 'changes in the precise embodiment of the invention herein disclosed can be inade Within the scope of Whatis claimed, without tie- D. order to release the hub it 1s necessary to 1npatingj from the spirit of the invention.

,in the aecoinpanying drawings the pre! ierred torni ott the invention has been shown.

'in said. draWings:-Figure l isa side ele ni ol the loci; applied te the rear hub ot icycle` a portion ci the lock casing being ,lien away. Fig. is a front elevation of the parts shown in llig. L Fig. 3 is a side elevation oit the hub engaging ring; of 'the lect' lis. 4 isr an edge View of said rin@ l' lier-ring to the ifngures by characters of rein-ence A. designates the hub of a bicycle whccl and Wherelthis hub projects laterallybcyond the spoke, engaging ilange it is provided with one or more flat faces C. il. ring., such as shown'at l3 is adapted to be placed on this projecting portion of the hub a zal has its inner edge formed with straight portions adapted to lit'upon the flattened portions C of the hub. Thus itWill be seen wat the ringr cannot rotate independently the hub after it has once been placed inl :ition thereon. A. series of slots or re- 'termed in the neriphery of the V cees es of the series located i desired distances apart. A lock cas` ing 4 is supported under the ring 1- by an arm 5 which is bolted or otherwise secured to the axle D on which the hub A 'is mounted. Another arm' 6 extends from the lock casing 4 and is adapted to be bolted ,or otherwise secured to the frame of the Vehicle. rilnus it will be seen that the lock casing' is held iXedly against movement iveA 11o the ira-nie. The lojclt 4easing carries-a spring pressed bolt 7 one end of which is normally projected against the kring l so as to become seated Within any one of the recesses 3 Which may be brought into register therewith. A spring dra-Wn pin 8 is slidably `mounted Within the casing 4 and is adapted, When the bolt is retracted into the casing 4to engage a shoulder 9 on said bolt and thus hold said bolt in retract-ed position and with its spring 10 under compression. l' v When it is desired to lock the hub againsty rotation, the pin 8 ispushed relative' to casing 4 in `any suitable manner so as to become disengaged from the shoulder 9. Spring 10 promptly forces thebolt 7 longitudinally so f as tot-brow it against the ringl whereby it will become seated Within the first recess 3 brought into register therewith..` After Ithe bolt has thus @en projected it 'becomes impossible to rotateA the hub B because it ,is

securely lockedto the fixed casing 4.' In

vthus be held retracted until' the fpin is again l'pushed out of normal position whereupon. the action liereinbefore described Will' be repeated. ln the drawings 'the key has been indicated at il. l Y I y importance is attached.. to the fact that the loclzlconstitutin the present invention is very compact in rorm `and can be readily applied to bicycles already constructed.' If preferred, however, instead of providing a ring` l 1which is separate from the hub, recesses euch as shown at 3, may be formed in the hub ost 'the vWheel and the lockl casing 4 can be niade Vintegral part of the vehicle :los

traine. This arrangement of parts is so obrvious that itis not deenied necessary to illus y, firm 6 herein descrmd..
